BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator having a plurality of storage chambers, at least two of which are arranged side by side and a partition wall filled with a heat insulating material.

2. Description of the Related Art A conventional example will be described with reference to FIGS. In the figure, a refrigerator main body 1 is composed of an outer box 2 and an inner box 3 and a heat insulating material 4 filled between both boxes. The main body 1 is composed of a plurality of storage chambers. A freezing chamber 5 is provided on the upper right side, a partial chamber 6 is provided side by side on the right side, a partial chamber 6 is provided on the upper left side, a refrigerating chamber 7 is provided on the central part on the right side, and a vegetable chamber 8 is provided on the lower right side. Each storage room is composed of a small room 9 on the lower left side. Each storage room is partitioned by a partition wall, and independent temperature control is performed. The freezing compartment 5 and the partial compartment 6 are partitioned by a partition wall 10 filled with a heat insulating material 4, and a front contact plate 11 is provided at a front portion of the partition wall 10.
A back plate 12 is fitted and fixed between the front contact plate 11 and the partition wall 10. Inside the partial chamber 6, a storage shelf 13 for storing stored food is placed on a shelf receiver 14, and an independent chamber 15 is provided in the lower part, and the top plate also serves as a storage shelf.
16 is placed on the guide rail 18 and is also a transparent independent room door 17
Is engaged with the guide groove 19 of the guide rail 18 so as to be able to open and close so as to slide the guide pin 20 of the independent chamber door to form the independent chamber 15. A temperature control device 18 is housed in the back of the independent chamber 15, and the amount of cold air supplied to the partial chamber 6 is controlled by the built-in damper thermostat to keep the temperature constant in the partial temperature zone.

In the structure as described above, the width a of the frontage of the partial chamber 6 is set by the front contact plate 11 and the inner box 3. The width b of the inner space of the partial chamber is such that the side wall 10a of the partition wall 10 and the side wall 3 of the inner box 3 are substantially flush with the front contact plate 11.
Although it is set with a, the partition wall side wall 10a and the inner box side wall
3a is a partial chamber 6 due to the draft provided to facilitate removal from the mold when the inner box 3 is molded.
It is inclined to the side, and therefore is smaller than the frontage width dimension a. The relationship at this time is a> b. Partition wall 10
Is the foamed polyurethane insulation 4 filled inside,
The freezing chamber 5 cooled to -18 ° C and the partial chamber 6 cooled to -3 ° C are adiabatically partitioned. This partial chamber 6 maintains freshness for a long period of time by keeping the water contained in the food in a slightly frozen state, and in order to keep a very narrow slightly freezing temperature zone at room temperature, the outside temperature is, of course,
Since heat transfer with the adjacent freezer compartment 5 must also be minimized, a thick heat insulating wall is required. The independent chamber door 17 provided at the lower portion of the partial chamber 6 has a guide pin 20 provided on the side surface thereof engaged with the guide groove 19, and the guide pin 20 slides along the guide groove 19. By moving it, it opens from the lower side to the upper side as shown by the chain double-dashed line in the figure, and it is possible to take out the food stored inside, but this guide rail 18 is as described above. For the reason, since the partition wall 10 cannot be made thin in a concave shape, it is provided so as to project from the side wall 10a. A guide rail is provided so as to face the inner box side wall 3a as well, but the width c between the guide rails 18 is c.
Is smaller than the partial guide width b,
The relationship of b> c is satisfied, and the width d of the guide rail 18 is smaller by a total of 2 left and right sides. Therefore, the relation including the width dimension is a>b> c, and c = a-2d.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the above configuration, when the freezing compartment 5 and the partial compartment 6 are arranged side by side, the partial compartment 6 is wider than the general proportion of the food storage amount. Since the size is set narrow, the size of the stored food is limited, and it is difficult to put the stored food in and out, and the guide rail 18 is provided so as to project from the inner box side wall 3a and the partition wall side wall 10a. Therefore, the width of the food that can actually be stored is smaller than the opening dimension a and the room width dimension b as shown in the dimension c, and food juice is collected because it is uneven in the partial chamber b. There was a problem that it was easy to get dirty and it was difficult to clean the room, which should be clean.

The present invention is to solve the above-mentioned conventional problems, and to eliminate protrusions such as guide rails of the independent door of the storage room, to make the room wide, and to make it easier to clean and to keep the room clean. The purpose is to do.

Means for Solving the Problems In order to solve the above problems, the present invention fills a partition wall that divides a storage chamber with a heat insulating material to make the wall thickness smaller than the front contact plate and by the front contact plate and the partition wall. A guide rail for a partial indoor / independent room door is provided at the step portion formed.

Action The present invention has the above-described configuration to widen the width of the independent room door guide rail portion to be substantially the same as the front dimension, thereby reducing unevenness in the room.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. The refrigerator body 1 has an outer box 2 and an inner box 3
And a heat insulating material 21 having a smaller thermal conductivity than that conventionally filled between both boxes. The refrigerator 5 and the partial chamber 6 are partitioned by a partition wall 10 filled with the heat insulating material 21, and a front contact plate 11 is provided in front of the partition wall 10 between the front contact plate 11 and the partition wall 10. The back plate 12 is fitted and fixed to the.
A storage shelf for storing stored food on the upper part of the partial chamber 6.
13 is placed on the shelf receiver 14. In addition, an independent room 15 is provided at the bottom, and a top plate 16 that doubles as a storage shelf is used as a guide rail 18.
The transparent independent chamber door 17 is openably and closably engaged with the guide groove 19 of the guide rail 18 so as to slide the guide pin 20 of the independent chamber door to form the independent chamber 15. ing. A temperature control device 18 is housed inside the independent chamber 15. In the side wall 10b on the freezer compartment 5 side, the partition wall 10 is substantially flush with the back plate 12, but in the side wall 10c on the partial chamber 6 side, the thickness of the partition wall 10 is set small. Therefore, a step d is formed between the front contact plate and the back plate 12. A guide rail 18 is provided so as to have substantially the same thickness as the step d and to be substantially flush with the back plate 12.

In the structure as described above, the width a of the frontage of the partial chamber 6 is the same as the size a shown in the conventional example. The width e of the interior of the partial chamber is set by the inner box side wall 3a and the partition wall side wall 10c which are inclined toward the room side of the partial chamber 6, but is larger than the frontage dimension a because the step d is provided. ing. The relationship at this time is e> a. This partition wall 10
Although it is set to be thin, since it is filled with the heat insulating material 21, there is no temperature influence due to heat transfer from the freezer compartment 5. The independent chamber door 17 provided in the partial chamber 6 is openably and closably engaged by the guide pin 20 sliding along the guide groove 19 of the guide rail 18. Since the partition wall 10 side of the guide rail 18 is provided in the step portion d, the width f between the guide rails 18 is narrower than the frontage dimension a, but the guide rail 18
It is only reduced by one thickness. That is, f = a-
The relationship is d. Therefore, the partial space frontage a
As compared with the above, the indoor width dimension e, which is the effective width dimension, can be made large, and even in the smallest guide rail dimension f, the thickness d corresponding to 181 guide rails can be reduced. The indoor width e can be used as effectively as possible.
Further, the front portion 18a of the guide rail 18 on the partition wall 10 side is attached to the back plate 12
By extending and contacting the back plate 12, the back plate 12 can be made substantially flush with the back plate 12 and the unevenness in the partial chamber can be reduced.

EFFECTS OF THE INVENTION As described above, according to the present invention, the partition wall filled with the heat insulating material is set to be thinner than the front contact plate, and the guide rail of the independent room door is provided at the step formed by the partition wall. Since the size can be set large and food can be stored more effectively, and the unevenness in the room can be reduced, dirt due to food juice etc. does not collect easily and wiping and cleaning are easy even when it is dirty It is suitable for food storage because it can clean the room and keep it hygienic.
